If you've had one or two bad nights lately, you can probably solve the problem by taking some of the measures below. These strategies may require you to change your sleeping habits, but the effort is well worth it in the long run.
1. Make your bedroom a haven for sleep. Your room should be quiet and sufficiently dark, because darkness prompts the pineal gland to produce melatonin, the hormone that regulates circadian rhythms (your 24-hour body clock). Heavy drapes can help keep the light out, and a fan or white-noise machine can help drown out any annoying sounds. Cool temperatures help you sleep, so set your thermostat appropriately. For better air circulation, open a window or use a fan. If the air in the room is too dry, buy a humidifier.
2. Become a creature of habit. A nighttime routine can be very effective in letting your body know when it's time to sleep. Go through whatever rituals help you get mentally prepared for sleep. (Read a few pages of your novel, spend 5 to 10 minutes on personal grooming, meditate, stretch.) It's also critical to go to bed and get up at the same time every day -- even on weekends.
3. Reserve your bed just for sleeping and sex. Avoid working, paying bills, reading, or watching television in bed. If you associate your bed only with sleep, you'll be more likely to fall asleep when you get under the covers for the night.
4. Tame your tummy. Going to bed either hungry or too full can disrupt your sleep. Don't have a big meal too close to bedtime or the digestion process might keep you awake. Also, if you lie down after stuffing yourself you can end up with gastric reflux -- stomach acid backing up into the esophagus. If you're hungry, have a snack rich in carbohydrates, which trigger the release of the brain chemical serotonin, associated with relaxation. Try a graham cracker or bowl of cereal. Pair it with some milk or a slice of turkey, both rich in the amino acid tryptophan, which also induces sleep.
5. Watch the caffeine. Too much caffeine throughout the day, even if it's not consumed right before bedtime, can contribute to fitful slumber. Once you hit 50, your metabolism slows, so caffeine may stay in your system longer -- up to 10 hours. Limit yourself to two cups of tea, coffee, or cola, taken at least 6 hours before bedtime. If that doesn't work, try cutting out caffeine altogether.
6. Tap the exercise answer. It's a simple fact: If you're physically tired at the end of the day, you'll sleep better. In a study from Stanford University School of Medicine, a group of 50- to 76-year-olds who had complained of sleep problems began moderate exercise for about half an hour four times a week. Compared with a similar group of people who didn't exercise, the more active group slept an average of one hour more each night, took less time to fall asleep, spent less time napping, and reported an overall improvement in sleep quality. Outdoor exercise is especially helpful. By exposing yourself to sunlight (particularly in the afternoon), you help prevent midday sleepiness and reinforce your body's circadian rhythms. Exercise at least three hours before bedtime.
7. Soak it up. Take a warm bath an hour or two before bed. Your body temperature will slowly drop after you get out of the tub, making you feel tired. Don't bathe right before bed, however, because it can briefly stimulate you enough to make it hard to fall asleep.
8. Drift off naturally. Investigate the benefits of chamomile, valerian, kava, passionflower, skullcap, catnip, or hops. These herbs can be taken in tea and other forms. A cup of chamomile tea before bedtime may be all you need to relax. If you're trying valerian, the suggested dose for the concentrated form is equal to two to three grams of the root a day. But don't combine valerian with alcohol or mood-regulating drugs. If you're using kava, try a dose of between 60 and 120 mg before bedtime.
9. Don't toss and turn. If 30 minutes go by and you haven't fallen asleep, don't lie in bed feeling frustrated. Get up and do something relaxing, like listening to soothing music or flipping through a magazine. Or make yourself a cup of warm milk.
10. Buy the right bed. A bed that's too soft can cause poor sleep postures (which can also lead to muscle stiffness and back problems). If you're leaving a divot in the mattress when you get up, it's too soft. Replace your mattress if it's more than 10 years old, and buy one that's as firm as you can tolerate but still comfortable.

假設(shè)你最近連著一兩天都睡不好,看起來不是很嚴(yán)重的事情,但是事情可能不像表明看起來這么簡單。這里我們可以推薦幾個(gè)辦法——改變你的睡眠習(xí)慣——雖然麻煩了點(diǎn),但是長遠(yuǎn)看還是值得的。
1. 把你的臥室變成睡眠天堂。首先,你的臥室必須安靜、黑且暗,因?yàn)楹诎档沫h(huán)境會(huì)促進(jìn)松果體產(chǎn)生褪黑激素,這種激素正是控制晝夜循環(huán)的(就是你那個(gè)24小時(shí)制的生物鐘)。用厚重的窗簾(或者別的什么)隔絕外界光源,借助風(fēng)扇或者白噪音掩蓋惱人的聲音。涼爽的溫度有助于入眠,所以恒溫器也要好好調(diào)節(jié)。當(dāng)然啦,開窗或使用電扇對(duì)室內(nèi)空氣循環(huán)有好處。如果室內(nèi)空氣太干燥,也可以用點(diǎn)加濕器。
2. 順從你的天性。晚上你會(huì)比較容易切換到睡眠狀態(tài),因?yàn)槟愕纳眢w知道——到點(diǎn)了。可以隨便做點(diǎn)什么以使在心理上做好入睡的準(zhǔn)備。(讀幾頁書、花個(gè)5到10分鐘打理個(gè)人衛(wèi)生,或者冥想一會(huì)?) 每天按時(shí)上床和起床也很重要——即使是在周末。
3. 保證你的床只是用來睡覺和xx。避免在床上工作,付賬單、讀書或者看電視。如果你希望只把睡覺這件事和你的床聯(lián)系起來,那么在床上你需要做的事情就是熟睡,而不是整晚翻烙餅。
4. 馴服你的胃。 無論太飽或者太餓都會(huì)干擾睡眠。別在臨睡前吃大餐,或者饑腸轆轆不得入眠。另一方面,如果你放倒的時(shí)候胃里還是塞得滿滿當(dāng)當(dāng),那么胃酸會(huì)回流進(jìn)食道。 如果真的很餓,吃些富含碳水化合物的小點(diǎn)心,可以觸發(fā)大腦血清素的釋放,這玩意有助放松身心。試試看全麥餅干或者一碗麥片。搭配牛奶或一小份火雞肉,這些食物富含氨基酸,同樣促進(jìn)睡眠。
5. 警惕咖啡因。 每天過量的咖啡因,即使不在睡眠時(shí)間發(fā)揮影響,也會(huì)導(dǎo)致睡眠不規(guī)律。當(dāng)你50歲時(shí),新陳代謝會(huì)變慢,于是咖啡因滯留人體的時(shí)間就更長——乃至于10個(gè)小時(shí)。睡覺前6小時(shí)最多只能來2杯茶/咖啡/可樂。如果這樣還不行,那就把咖啡因戒了。
6. 累了就睡。事情其實(shí)很簡單:如果你的身體覺得累了,那么入睡就很容易了。斯坦福大學(xué)醫(yī)學(xué)院的一項(xiàng)研究,要求一組年齡在50-76之間有睡眠障礙的受測人員,為時(shí)一個(gè)半小時(shí)的中等強(qiáng)度的鍛煉,每周進(jìn)行4次。相較于情況類似而沒有參加運(yùn)動(dòng)的其他受測小組成員,參加運(yùn)動(dòng)的成員每晚的平均睡眠時(shí)間增加了一個(gè)小時(shí),入睡時(shí)間則更少,短暫睡眠的時(shí)間更短t,而且根據(jù)報(bào)告,睡眠質(zhì)量有整體提高。戶外運(yùn)動(dòng)尤其有效。 暴露于日光下(尤其是午睡),(容我碎碎念一句,不怕皮膚癌么?), 有助于避免午睡,鞏固人體生物節(jié)律。睡覺前鍛煉3個(gè)小時(shí)。(到底該不該午睡啊,我覺得不太靠譜……)
7. 沖個(gè)澡。臨睡前1到2小時(shí)來個(gè)熱水澡。當(dāng)你離開浴盆體溫會(huì)逐漸下降,令你感到疲倦。不過,別臨睡才洗,那會(huì)使人興奮,反而睡不著。
8. 回歸自然。甘菊,纈草,卡瓦胡椒,,西番蓮,美黃芩,貓薄荷(我靠!),啤酒花被證明是有效的。 這些草藥可以加進(jìn)茶或者別的什么里。臨睡前一杯甘菊茶可以幫助放松精神。如果你愿意嘗試下纈草,建議的劑量控制為平均2至3克,每天。但是不要和酒精以及刺激性藥物混合使用。如果用了卡瓦,劑量要控制在60和120毫克之前,就寢前使用。
9. 不要勉強(qiáng)逐漸。如果半個(gè)小時(shí)還不能入睡,不必躺在床上暗自神傷。 干脆做點(diǎn)別的什么輕松一下,諸如聽點(diǎn)舒緩的音樂或者瀏覽雜志;蛘邅肀瓬嘏D。
10. 買張好床。一張床不能太軟,那會(huì)導(dǎo)致睡姿不正(還會(huì)導(dǎo)致肌肉僵硬和背部問題)。如果你起床的時(shí)候床墊凹下去一塊,那么這張床就太軟了。如果你的床墊的服役年齡高于10年,老兄,好換啦,換張硬度舒適的吧。
如果你不覺得困或者覺得不需要睡覺,那就別逼自己睡,等想睡了再說!
